Tru-Test Electronic Milk Meter is a patented, ICAR approved, portable device that will automatically record milk yield, automatically dispense a representative sample, read uniquely identified milk sample vials and communicate wirelessly with the Tru-Test Data Handler. The milk sample vials used with the Tru-Test Electronic Milk Meter can be uniquely identified by either barcode labels or by RFID tags. Sample vials do not need to be sequenced in trays. Tru-Test Electronic Milk Meter system can interface to animal RFID systems allowing fast, accurate and seamless linking of data and data integration.
